Gumstix® Overo® RoboVero™ Expansion Board

This standalone LPC1769 microcontroller board for robotics applications has onboard sensors, buttons, and LEDs. Numerous header pins for GPIO/CAN/I2C/SPI/UART/PWM and analog signals make this well-suited to motor control applications. Manage the Cortex-M3 from an onboard Overo COM or from an external USB interface using the HubCommander™ interface.

Features

The new HubCommander™ interface over USB lets an external host commandeer the onboard USB Hub and these devices:

Cortex-M3 JTAG

Cortex-M3 USB Device

Two (2) USB Standard A Jacks

Console for the onboard Overo COM (if present)

3-axis accelerometer

3-axis magnetometer

3-axis gyroscope

Coin cell backup battery holder

Three 3x10 headers:

Motor Header

7 lines each for power and return at motor voltage

6 PWM lines at 3.3V

10 motor control lines at 3.3V for control of one 3-phase AC or DC motor

AD Header

7 A/D lines

2 A/D reference lines

3 A/D power lines

SPI bus

7 GPIO

Power lines

Communication Header

2 two-wire serial ports

1 four-wire serial port

I2C bus

SPI bus

CAN bus

3 GPIO

Power lines

Note that some signals are multiplexed and share the same header pin (refer to schematic)
